Boasting 20 hours of continuous playtime, the SR35 deploys the first Dual/Quad DAC switching mode in the A&norma series, enabling users to easily adjust the sound and power output while improving power efficiency. The brand’s patented TERATON APLHA technology ensures balanced dynamics and class leading resolution throughout listening sessions.

Pocket powerhouse 

Elevating the series to new heights of audio excellence, the new SR35 is the first in the A&norma series to be equipped with New Generation AMP technology from Astell&Kern. Featured in the latest high-end A&ultima and A&futura range, the exclusive, in-house amplifier effectively eliminates noise at a high-power output to ensure SR35 listeners experience the clearest possible, distortion free sound at all times. The new amplifier technology built into the SR35 also boasts a two-step gain mode for the ultimate Hi-Fi experience. New gain settings generate a high current output to produce a consistently powerful sound with excellent driver control to ensure seamless use of sensitive IEMs and hard-to-drive headphones.

An interface fitting for listening excellence
